Abstract

A thermal elastohydrodynamic lubrication (TEHL) finite line contact model is developed for a helical gear pair lubricated with an Eyring fluid or a power-law fluid in order to investigate the effects of the working conditions. A lubrication analysis within a meshing period shows that the differences between the Eyring and Newtonian solutions mainly lie in the film temperature and the shear stress. For the power-law fluid, the power index n has a significant effect on the film thickness. The effects of load and speed on lubrication performance along the line of action are discussed.

The TEHL results of the whole meshing period: (a) variations in the ry,ue, (b) variations in the ξ, (c) the pressure and minimum film thickness of the meshing process for the central position of the contact line at x = 0, and (d) the temperature and friction coefficient results of the meshing process
